Answer:
9
Step-by-step explanation:
The range is the biggest number minus the smallest number
The biggest number in this set is 10
The smallest number is 1
10-1=
9
Step-by-step explanation:
let the cost of the item be y
for taxes
30%of y
30/100×y=3y/10
=0.3y
freight charges =65
total =520
0.3y+65=520
0.3y=520-65
0.3y=455
y=455/0.3
y=$1516.7
y≈$1517
Answer:
q= -40p+c
q= -40p+4,000
Step-by-step explanation:
$5 each for 3800 tye-dye shower curtains
$10 each for 3600 tye-dye shower curtains
Slope of the demand line is
3800-3600/5-10
=200/-5
= -40
Demand function is
q= -40p + c
Where c is a constant
For q=3800 and p=$5
Demand function is
q= -40p + c
3800= -40(5)+c
3800= -200+c
c=3800+200
c=4,000
Linear demand function is
q= -40p+4,000
Let's assign a variable x to the number of multiples for each pound of dry mix and water. With that being the said, the question for finding the total pounds would be:
Total pounds = x*Pounds of dry mix + x*Pounds of water
Total pounds = 60x + 8x = 68x = 14 + 1/6 = 85/6
x = 85/6 / 68
x = 5/24
Thus, the pounds of dry mix is 60*5/24 = 25/2 lbs, while the pounds of water is 8*5/24 = 5/3 pounds.
4(2x +5) = (8x + 20)
8x =20 is an equivalent expression
